Non-Markovian heat production in ultrafast phonon dynamics
Fredrik Erikssonm Yulong Qiao, Erik Fransson, R. Matthias Geilhufe +1
High-intensity THz laser pulses enable the light-mediated control of lattice vibrations by resonantly driving selected phonon modes. On ultrafast timescales, memory effects influen…

Quantum Enhancement of Thermalization
Yulong Qiao, Frank GroÃmann, Peter Schlagheck +1
Equilibrium properties of many-body systems with a large number of degrees of freedom are generally expected to be described by statistical mechanics. Such expectations are closely…

On the second law of thermodynamics: An ideal-gas flow spontaneously induced by a locally nonchaotic energy barrier
Yu Qiao, Zhaoru Shang
People are well aware that, inherently, certain small-scale nonchaotic particle movements are not governed by thermodynamics. Usually, such phenomena are studied by kinetic theory…
